Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
75 words
A radiating device comprising: an escutcheon of an electrical appliance, and a plurality of fin members fitted to said escutcheon for heat dissipation; said escutcheon having a plurality of openings each formed at a position adjacent to the base portion of the respective fin member, each of said openings being formed square, and each of said fin members being fitted to the escutcheon in such a manner that it is fitted in the associated opening.
Claim 2
Dependent Claim
75 words
A radiating device comprising: an escutcheon of an electrical appliance, and a plurality of fin members fitted to said escutcheon for heat dissipation; said escutcheon having a plurality of openings each formed at a position adjacent to the base portion of the respective fin member, each of said openings being formed square, and each of said fin members being fitted to the escutcheon in such a manner that it is fitted in the associated opening.
Claim 3
Dependent Claim
35 words
A radiating device according to claim 1, wherein each of said fin members is formed hollow so that the fin as well as the adjacent opening receives heat to be dissipated from within the housing.
